31257208 ÷ 853 
Let's see how many times 853 fits into 31257208.

Advancing to step 1:
If we divide 3 by 853, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 853

Step 2:
The number 853 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 853

Advancing to step 3:
853 can be fit into 312 0 times, resulting in a remainder of 312.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 312 and we're left with 312.
Take the next digit (5) from the dividend and append it to 312, then repeat: 3125 / 853

On to step 4:
When dividing 3125 by 853, we get 3 with a remainder of 566.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2559 from 3125 leaves us with 566.
Include the next digit (7) from the dividend after 566, then repeat: 5667 / 853

Step 5:
If we divide 5667 by 853, we get 6 and a remainder of 549.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 549 after subtracting 5118 from 5667.
Fetch the next digit (2) from the dividend, attach it to 549 and continue: 5492 / 853

On to step 6:
853 goes into 5492 6 times with a remainder of 374.
Write down 6 as next digit of the result. 
Result so far: 366.0
If we take 5118 away from 5492, we end up with 374.
Bring next digit (0) of the dividend behind the 374 and repeat the process: 3740 / 853

Moving on to step 7:
When dividing 3740 by 853, we get 4 with a remainder of 328.
The next digit of our result is 4. 
Result so far: 3664.0
Subtracting 3412 from 3740 leaves us with 328.
Include the next digit (8) from the dividend after 328, then repeat: 3288 / 853

Going ahead to step 8:
If we divide 3288 by 853, we get 3 and a remainder of 729.
The next digit of our result is 3. 
Result so far: 36643.0
Subtracting 2559 from 3288 leaves us with 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

On to step 9:
When dividing 7290 by 853, we get 8 with a remainder of 466.
Write down 8 as next digit of the result. 
Result so far: 36643.8
If we take 6824 away from 7290, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 10:
If we divide 4660 by 853, we get 5 and a remainder of 395.
Use 5 as the next digit of our solution. 
Result so far: 36643.85
If we subtract 4265 from 4660, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 11:
3950 divided by 853 is 4 with a remainder of 538.
Record the quotient 4 as the next digit in the result. 
Result so far: 36643.854
Deduct 3412 from 3950 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Let's proceed to step 12:
5380 divided by 853 is 6 with a remainder of 262.
Write down 6 as next digit of the result. 
Result so far: 36643.8546
If we take 5118 away from 5380, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 13:
When dividing 2620 by 853, we get 3 with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 36643.85463
Subtracting 2559 from 2620 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 14:
610 divided by 853 is 0 with a remainder of 610.
Put 0 as the next digit of the answer. 
Result so far: 36643.85463
The remainder is 610 after subtracting 0 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 15:
6100 divided by 853 is 7 with a remainder of 129.
Write down 7 as next digit of the result. 
Result so far: 36643.8546307
Subtract 5971 from 6100 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 16:
The number 853 fits into 1290 1 times, leaving a remainder of 437.
The number 1 becomes the next digit in our result. 
Result so far: 36643.85463071
Subtracting 853 from 1290 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

After the division, we end up with 36643.85463071 and a remainder of 4.37e-07.
